THREAD- PARTING MECHANISM FOR LOOMS.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed January 16, 1907. Serial No. 362,480.

To all whom it may concern:

vide the running shuttle with a fresh supply of filling.

Such a replenishing loom is, for example, shown in United States PatentNo. 529,940, granted'to Northrop November 27, 1894, looms of this typebeing technically known as Northrop looms. 1

When a change of filling is effected the old fillingend, (that is, thelength of filling leading from the cloth to the filling-supply in theshuttleand about to be abandoned,) must be severed and removed in orderto prevent it from being carried back into the cloth, or

from fouling the fresh filling inserted in the shuttle.

Means have been provided heretofore to part such filling-end adjacentthe cloth by means of a temple thread,-

cutter, and to part it near the shuttle by other means.

In my present invention I have provided means to part the old fillingadjacent the cloth, causing the operation of such means positively anddefinitely at the proper instant, instead of depending on the somewhatuncertain action of a temple thread-cutter. Herein such parting means isoperated a second time to part the new filling-end which eirtends fromthe fillingfeeder or hopper to the cloth after the first shot of thereplenished'shuttle, after which second operation the parting meansremains inoperative until the next filling replenishment is called for.Ihave alsoprovided novel means to part the old filling-end at theshuttle,- and as will appear hereinafter such parting 0r severance takesplace at a point nearly opposite the head of the filling-carrier in theshuttle and about to be ejected. This insures-a very short length offilling to be drawn out of the shuttle eye by theejectedfilling-carrier,

eliminating any fouling of the fresh filling simultaneously inserted inthe shuttle.

The length of filling severed by the two parting means is, inthe presentembodiment of my invention engaged by a thread-catcher, convenientlymounted .on the shuttle-feeler, the thread-catcher grasping'the scvcredpiece of filling and drawing it forward out of the way as the part onwhich the catcher is mounted returns to normal position -normalposition.

Referring to Figs. 1, 2, 3, 4 and,6.- thefilling-ieeder The opening andclosing of the clamping members or jaws of the thread-catcher iseffected automatically at the proper times.

The various novel features of my invention, one

practical embodiment whereof is illustrated in the accompanyingdrawings, will be fully described inthe subjoined specification andparticularly pointed out' in the following claims.

The tip-support] shown best in Fig. i is of usual con struction and ispivotally mounted on the bracket f X rigidly secured to the outer end ofthe stud f, and operates in usual manner. I v

In Figs. 4 and 6, I have omitted the tip-support and broken off thestand in order to show more clearly the parts which would be otherwisehidden.

The notched dog m pivotally connected at 2 with the downturnedbifurcated extension f of the trans ierrer, the hunter 0 on the lay tocooperate with the dog when filling-replenishment is to be effected, theshuttle-feeler arm y. fulcrumed on a short rocker-shaft i mounted on theloom-side, the shuttle-ieeler arm having a lug 3 Fig. 7, withWhich-cooperates the arm 11-, and the arm y having a cam-slot y tocooperate with the lug m on the dog at are all substantially as shown inUnited States patent to Stimpson No. 718587, dated 7 January 13, 1903,the lower end of the arm 1 being rigidly connected with the rocker-shafty in any suitable manner. I/

In the present embodiment of my inyention, the 'shuttle-feeler arm g notonlyis arranged to feel for and ascertain whether the shuttle isproperly boxed in the box B when replenishment of filling is called for,but

. 1 A it also carries a thread-catcher, to be hereinafter dethe shuttle.

An upturned arm 5 is rigidly bolted at its lower end at 6 to the innerface of the bracket f said arm having an inwardly and horizontallyextended pin 7 at its up-. per end, on which ismounted an elongatedsleeve-like hub 8, shown as a part of a casting constituting a blade--earrier, said casting comprising an elongated depending key 9, having aforwardly extended offset 10 to tho apex of which at 11 is attached aspriifg 12, clearly shown in Fig. 4, the lower end of the spring beingin turn secured. to a lateral lug 13 on thetransferrer, and

extended L-vlow. the face 14 of the-offset 10.

The blade-carrier is adapted to swing onthe pivot or fulcrum pin 1.reward and from .the lay, and when the transferrer is is normal orretracted position, see Figs.

,3 and 4, the lug 13 acting uponthe iace 14 positively moves theblade-carrier forward into inoperative position.

When the transierrer is operatively moved, to transfer a fresh supply offilling from the feeder to the shuttle, the yielding connection l2between the transferrer and blade-carrier operates to swing the latterrearwardly into operative position, shown in Fig. 6.

The blade-carrier swings in a path parallel to and near the path ofmovement of the transferrer, as will be manifest from an inspection ofFigs. 1 and 2, and as the transierrer engages the head of thefilling-carrier or bobbin to be transferred, it will be manifest thatthe bladecarrier will move toward or from the shuttle at a point nearthe head of the filling-carrier therein.

The lower end of the blade-carrier is rearwardly extended at 15, and isprovided with a cutting blade 16,

see Fig. 5, to cooperate with a relatively movable blade 17pivotallymounted on a stud 18 extended through the blade-carrier.

The stud is held irom movement in the blade-carrier and at its inner endis enlarged to form a head 19, Fig. 5, and a barrel 20 around whichi's'coiled a spring 21.

one end of the spring being attached to the head 19 at.

22, and the other end of the spring is held a pin 23 on an enlargement17 of the blade. The spring not only serves to press the cutting edgesof the blades 16 and 17 together, but also normally 'acts to hold theblades open, tho movement of .the blade 17being lim ited by a pin'24 onthe blade-carrier extended through a slot 25 in the enlargement 17 Thesaid enlargement its upturned at its front portion to present a cam-likeface 26, and at its rear portion the enlargement 17 is upturned at 27,and provided with a lateral offset 28 extended above the toe 15 andacross-the rear face of usual opening for the introduction of the'feeler in a socalled feeler loom, the opening being near the head ofthe filling-carrier, and I have herein'shown the front wall of thereplenishing shuttle-box B as provided with an opening b so located thatwhen the shuttle is properly boxed lor replenishment, the openings s andb will register, 7 I

The blades on the blade carrier are arranged to move rearwardly into theaperture b when the blade-carrier is operatively positioned, and the laybeats up, as shown in Fig. 6, it being understood that the blades willbe open when they enter the aperture and they will remain open untilthey enter the opening-8 in the shuttle, receiving between them-the o'ldfilling-end.-

. It will be understood of course that the old filling-end leads fromthe eye of the shuttle between the front wall of the latter, and theinner 'facegof the box-walhthehce tejthel eloth at the replenishing sideof'the loom, and when the blade-c ier'ismoved into operative position byor through the actuz ition of the replenishing mechanisin, the oldfilling-end must be brought between the edges of'theblades;

. way portion A of the lay, so that there is practically To thoseskilled in the art, it will be plain that the lay must move forward fromthe position shown in Fig. 6, in order to complete the transfer of afilling-carrier from the feeder to the shuttle, a filling-carrier inprocess thereby turn the blade 17 on its pivot into the position shownin Fig. 6, to part the filling-end. As a matter of fact, the filling-endis parted before the transfer of filling is completed, but thecompletion of the forward movement of the lay will swing theblade-carrier forward slightly, the spring or yielding connection 12between said blade-carrier and the transferrer permitting such movement.As the lay goes back and the transferrer f returns to normal position,the bladecarrier is returned to its normal, inoperative position, andthe end 4 of the rod 3 acts to insure the opening of the blades, as hasbeen described. As the .old fillingend is parted substantially oppositethe head of the filling-carrier about to be ejected therefrom gt will beclear that a very short length of filling will remain to be drawn outthrough the eye of the shuttle, as such ejected filling-carrier isdischarged through the guideno chance for any fouling of the old fillingwith the fresh or incoming shuttle and absolutely no chance for the oldfilling to be carried back into the cloth.

If the shuttle-feeler. to be hereinafter referred to prevents theoperation of the replenishing mechanism,

the blade-carrier. will not be moved into operative,

position.

The operative positioning of the means for parting the oldfilling-endfat t-he'shuttle is effected by or through the operation ofthe filling-replenishing mechanism, as has been described, and theactual closing of the parting members or blades to partthefilling-end ispositively effected by or through the lay on its forward beat' at thetime of filling-replenishment.

It is necessary to part the filling-end adjacent the cloth at thereplenishing side of the loom, and this has been accomplished heretoforeby so-called temple thread-cutters and by other devices more orless'positive' or definite in theiraction, but in actual practice thesedevices have. at times failed to part the old filling endwith thecertainty and positiveness which is desirable, and at a definite time.

The parting means embodied-in my present invention for. parting thefilling-end adjacent the cloth is controlled as to its operation by orthrough the actus tion of the replenishing mechanism, and is actuatedpositively and at a definite time, and I have so arranged the mechanismthat it not only parts the old filling-end,

but it also parts the new filling-end'du'eto filling 50, Fig. 1. I Thelink member 49 extends to. the fight toa bell- "crank 51, 52, mounted toin a substantially liori-- replenishment.

\ Referring to Figs. 1, l2 and 13, I have shown a temple T of suitableconstruction, mounted on the-breastbeam of the loom at thereplenishingside thereof, the

temple shank having the usual dependi ng heel tto be gated slot 31 inits top, the housing having slidably see Figs. 14 and 15', to theextremity of which is rigidly attached an upper blade 33, a cooperatingblade 34 being pivotally mounted on the blade-carrier at 35, and havingan upturned lug 36, extended through the slot 3]: A fiat spring 37' on'the blade-carrier presses at its free end upon the pivoted blade 34 andmaintains it yieldingly against the cooperating blade 83, to insureproper cutting action. The blade-carrier is provided with a dependingheel 38 and isalso forwardly extended topresent a flattened andelongated extension 39 longitudinally slotted at 40 to receive aguide-lug 41 extended laterally from the temple stand T .The extensionhas an upturned shoulder or abutment- 42, and a forwardly extended,rigid rod 43, slidable in a guideear 44 on the temple-stand. I Betweenthe abutment or' shoulder 42 and the guideear, a spring 44 isco'iledaround the rod 43 to move the blade carrier in the direction of thearrow 45, Figs. 12 and 13, when the spring is free to act.

When the blade-carrier is in its normal position, Figs. 12 and 13, andfull lines Fig. 14, the two blades are Iretracted within the housing andare open, see Figs. 13 and 14, the opening of the blades being caused byengagement of the lug 36 with the front end of the slot 31 in thehousing.

When the blade-carrier is moved rearwardly by the action of thespring'44 the blades willmove out of the housing bodily and in theiropen position, see dotted lines Fig. 14, until the lug 36 strikes therear end of the. slot 31, whereupon the blade 34 will be swung upward onits pivot 35 into the closed position, see Figs 15,

such positive closing thereof will part the filling posi- "in Fig. 1 3,and in full lines Fig. 14.

I have provided a detent instrumentality to normally retain the partingmeans in the position shown in Figs.

12 and 13, and also in Fig. 1, the detent in the presentoperativeposition byor through the actuation of the "replenishing mechanism.

The temple stand T hasa rigid,'laterally-extended pinyifi behindtheshoulder or abutment 42, and upon the piii is slidably mounted adetent shown as a block 47; rigidly attached to one member as 48 of anadjust- .able link 48', .49, the overlapped ends of the two link membersbeing adjustably connected by clamping bolts Zontal plane on'an uprightpost 53 on the filling-feeder stand, a suitable spring '54 acting'upo'nthe bell-crank to normally maintain itin the position shown in Figs.

tively and effectually. If new the. parts are in the position shown inFig. 15, and the lay beats up, a part a of the latter willstrike theheel 38 and will move the embodiment-0f my invention being withdrawn mmmounted within it the rear end-of a blade-carrier 32,

and if the filling is caught betweenthe open blades,

the parts will thereby be restored to the position shown '1"andI2, withthe detent 47 in cooperation with the Y The bell-crank arm 52 isdownturned at 53, adjacent to and in front of the depending extension f3 of the transferrer, so that when the latter is rocked to effectfilling replenishment, the bell -crank will be turned in the directionof the arrow 54, Fig. 1, to pull the link 48, 49

to the right, and thereby withdraw the detent 47 from the fillingextending from the cloth to the shuttle in -'the shuttle-box B), andthereafter to close the blades upon and part such filling-end.

It will be" understood that when the lay is fully forward, theengagement thereof with the heel 38 prevents the operation of theparting means until the backward swing or movement of the lay followingreplenishment, but when the transferring mechanism and'lay are in theposition shown in Fig. 6, the detent 47 is withdrawn and the blades 33and 34 would operate to part the filling adjacent the cloth.

.By the two separate parting means above described, the old filling-endis parted in twoplaces, at the edge of the cloth and at the shuttlerespectively, and after replenishment the shuttle is shot across thelay, and the fresh filling is laid while the new filling-end, leadingfrom-the hopper or filling'feed-er to the nearer edge of the cloth isleft, and I have provided means which i I will now explain whereby onthe next forward beat of the lay, a second'operationof theparting meansadjacent the edge of the cloth.will be effected to part' the'newfilling-end. If nothing were provided to prevent it, the next forwardbeat of the lay after replenishment would cause the blade-carrier to bemoved.

forward'and the spring 54 would return the bell-crank and the adjustablelink 48, 49 to normal position, to

' thereby return thedetent 47 to operative positiomand there couldnot'be two successive operations of the partirig means. Herein, however,I retard the restoration of the parting means to normal or inoperativeposition,

. and during the retarded period, the lay acts to cause a second partingoperation, to part the fresh filling-end; "An upturned and rearwardlyextended linger '55 is foimed on the slotted plate 56 which restsuponthe' member 49 of the link and 'isclamp'ed thereto by the bolts 50,the said finger being'normally' on the left of a retarding member 57',Figs. 1 and; 12, and in the present embodiment of my invention," I haveshown such retarding member as a prolongation of the upper end:

' of the vibrating actuator or weft hammer W of the filling-detector orfork w at the right hand side of the loo'm. v

The vibrator W is at its extreme rear position, and is just about tomove forward when theshuttle is picked -across to the replenishing-sideof the loom, so that if the When the vibrator is in its rear-mostposition, there- 'tarding levice57 is beyond therear end of the finger55, so that the actuation of the replenishing meehan'ism of the throw ofthe detent,

is free to withdraw thc deteni. 47, and thereupon the finger 55 is movedto the 'right'ef' thpaeieof movement of the retarding device 57 viewingl, and such retarding device willbe moved forward into position toengage the finger, but on the opposite side thereof, beforethe'return-of the replenishing mechanism to normal position has releasedthe bell-crank 51, 52. Con= sequently as the vibrator or weft-hammer Wmoves forward, it will then wipe over the; left hand face of the finger55 and will prevent the return oftlie detent 47 to operative positionfor the time being. i

The fresh filling having been shot across, the new filling-end ispresent between the cloth and thefillingfeeder, and as the lay beats up,it engages the heel 38 of the blade-carrier, the parts then being in theposition shown in Fig. 15, and the parting mechanism 'is restored to thecondition shown in full lines Fig. 14, as the lay completes its forwardmovement. The fresh filling is thereby beaten in, and as the lay swingsbackthe spring 44 operates to project the blades 33, 34 in'openposition, see dotted lines Fig; 1.4, to receive between them the freshfilling-end, and as the lug 36 hits the rear end of the slot 31, theblades will be closed upon'and will part such'new or freshfilling-end.By this time,

however, the vibrator W has again assumed its rearmost position,releasing the finger 55 and thedtent, which latter by the action of thespring 54 will press against the side of the shoulder or abutment 42;

When on the next forward beat of the lay, the heel'BS is engaged, theblade-carrier and'shoulder or abutment- 42 will "be moved"forwa1-d, thelatter beyond the detent,

so that the detent will snap into place in its operative "position, asin Figs. 12 and 13, so that "when thelay swings back the abutment willbring up against the detent and the parting mechanism is' therebyretained in inoperative position with theblad'es retracted or housed,

untilthe-next replenishment of filling-is called for. When such'partingmechanism is 'in normal position,

the two heels 38 and tare so positioned with relation'to each other asto bepractically engaged simultaneously on the beat-up ofthe lay, sothat the temple is moved forward and the parting means bodily therewith,the temple shank-sliding in the stand T in usual'manner, but as theparting means move forward with the temple, the bladesj'will remain'retractedwithin the housing, and heneecannot interfere with the fillingwhen "the shuttle is boxed at 'the replenis'hing'side of the loom andthe loom is running properly.

The adjustable connection between the two parts 48, 49'of the link andthe blade .56 prov'idesfor adjustment and for regulation of theretarding finger 55. i f

So far as theretarding device is'concerned, it need not necessarily be apart of the weft'hammen as any vibrating member timed 'to vibrateproperly will operate in'the same manner, but in the case of adoublefork loom, the weft hammer of the right hand fork affords at oncea-proper and very convenient retarding device to operate as has beendescribed.

, When the detent has been withdrawntopermitthe spring 44 to operate theparting means, the rearward movement of the blade-carrier 32 is limitedby the engagement of the shoulder or abutment42 with the pin 46 on thetemple stand.

if the shuttle is properly boxed, the jaws 58 and 64 will move acrossthe raceway oi the lay close to the inner end of the shuttle, andfillingsreplenishment will follow,

but if the shuttle is too far out of the box, the ends of the jaws willengage the side wall of the shuttle, and prevent filling-replenishmentin a manner common to looms of this type. A lateral pin 67 on thejaw-carrier 62 passes loosely through aslot 68 inthe branch 60, see
